I put the code snippet in and captured some of its output, and caught
about 4 HandlePropertyNotify calls in gdb. Hope this helps.

Interesting. Fvwm should not be in the HandlePropertyNotify()
function at all. My guess is that either an innfinite number of
PropertyNotify events is generated by the application, or that
fvwm receives the same event again and again. Can you please add
this code at the front of the HandlePropertyNotify() function in
events.c (line 2526), right after the "DBUG" statement:
---------------------------- snip ---------------------------
fprintf(
stderr, "pn: ser 0x%x time 0x%x atom 0x%x w 0x%08x '%s'\n",
(int)te->xproperty.serial, (int)te->xproperty.time,
(int)te->xproperty.atom, (int)te->xproperty.window,
(fw) ? fw->visible_name : "(null)");
---------------------------- snip ---------------------------
And post a few lines from the end of the output once it is hung?
THis should confirm either of my theories. If the numbers "ser"
and "time" do not change, it is the same event again and again.
In any case, can you repeat the single stepping session until it
enters HandlePropertyNotify() for a second time, please? Just
hold down the return key in gdb and wait until you have seen the
"fprint" from above two times.
